Firstly talking about renewables confuses things, the idea of renewables looks like something devised by those believing fossil fuels are good and necessary.
There is only one energy, it comes from the sun, and isn’t renewable.
When we sort that out it becomes clear that we have never produced energy, only converted it fron various stored forms on Earrh, sold that, and consumed it.
So our entire existence has been a process of reducing energy on Earth, in other words energy extraction.
In fact our financial debt is actually an energy deficit to our planet.
The only way it can be paid back is by harvesting the energy of the sun, and doing work with that to repair the various damages done by our history of extraction.
When we look at how to do that, do like trees, create, build, expand, and replicate structures that supply everything needed by humanity, entirely funded/fuelled from the energy of sunlight, we realise there is no profit in the business model, but infinite free money for all people, which removes the clout of all capital, in fact reduces it to zero.
That is because the solar energy already in use is continuously adding an invisible physical energy product to the global capital base which is not reflected by the issue of money.
Honestly reflecting that requires that free money is issued to all people.
That also completely changes our conception of how useful solar energy is.
By the old system it might be argued or perceived that it doesn’t have enough energy density, but that does not reflect nature, thus is not reality.

That is the real reason the old system is not sustainable, it is not reality.

In reality the sun powers all of nature.
By the new system of reality we see the sun is the souce of all energy and thus all wealth, just like physical nature.
Some might call that delusion.
I call it a specialism of Systems Engineering, "Kardashev Engineering".
We can choose to see it, use it, and survive as a species or not.
That seems the real choice to me.
